Great atmosphere and awsome people! Little over 2 weeks out from a pro fight and all I can say Is I'm very glad I chose this gym to for my stay in town! Works for all levels!

★★★★★ — Alvin, Mar 2025

I joined Insurgent about 8 months ago. I could not be happier with my choice to start. This is an amazing group of very welcoming people committed to improving their martial arts skill and physical health. The gym is one of, if not the nicest gym in town. It's has all the equipment you could want and plenty of space.

★★★★★ — Luke, Mar 2025

Insurgent Fitness has been the best gym and martial art place I have ever trained at. They are all so kind not just the staff, but the other students as well. I couldn’t say enough about Insurgent as there has been no yelling and everyone is willing to help walk you through the drills.

★★★★★ — Mia, Apr 2025

Great place to get in a solid workout in flagstaff. Was in town for a week and used the facility almost every day. Have everything you need to get in a solid workout from free weights to cable machines to platforms. All types of barbells and plenty of room.

New to muay thai? Start at Insurgent Fitness

Insurgent Fitness comes up as a beginner-friendly gym — noted on their own site. If you've never thrown a punch or a kick, that's exactly who a good beginners program is for. A few things worth knowing before your first week. First, you don't need to be fit to start — you get in shape by training, not before it, and coaches scale the conditioning to you. Second, you won't be thrown into sparring — reputable gyms build fundamentals (stance, footwork, and the basic strikes of the "art of eight limbs") for weeks before any contact, and sparring stays optional. Third, all levels really are welcome — ask about a dedicated beginners or fundamentals class time so your first session is alongside others who are also starting out. Most gyms are happy to let you watch or try a class first, so reach out before you commit.

Your first muay thai class at Insurgent Fitness

Nervous about walking into a muay thai gym for the first time? Almost everyone is, and good coaches expect beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, then drilling the basics on pads and bags — not fighting. Rest whenever you need to; no one will bat an eye. What to wear: shorts or athletic wear and a t-shirt; you'll train barefoot on the mats. What to bring: water and hand wraps if you have them — many gyms lend gloves for a first class, so it's worth asking when you call. As you keep training you'll add your own gloves, wraps, a mouthguard, and shin guards. Sparring is optional and comes later, once your fundamentals are solid. Arrive 10–15 minutes early to sign a waiver and meet the coach. It gets easier fast — most people feel far more at home by their third class.

Muay thai is a contact sport. Ease in, listen to your coaches, and if you have any injuries or health concerns, mention them before class and check with a doctor if you're unsure.
